9DOF Quadcopter Flight Controller

Description

What it is

The 9DOF STM32F103 Quadcopter Controller is a module for drones that integrates high-precision sensors and a powerful microcontroller. This device combines an accelerometer, gyroscope, and magnetometer to provide data on position and orientation.

Features

• 9DOF Sensor (MPU6050 + HMC5883L)
• STM32F103 Microcontroller

What it is for

Ideally suited for makers who want to build an autonomous drone, this module can be used to stabilize the quadcopter’s flight and acquire data on position and orientation. It is compatible with Arduino.

Tutorial: How to Use Quadcopter 9DOF STM32F103 + MPU6050 + HMC5883L

The 9DOF STM32F103 quadcopter with accelerometer and gyroscope MPU6050, and magnetometer HMC5883L is ideal for makers who want to build an autonomous drone. This module offers a combination of integrated 9DOF (degrees of freedom) sensors with a powerful STM32F103 microcontroller, making it suitable for both manual piloting and automated flight.

What you need

• Arduino IDE
• USB A-B cable
• STM32 development software (optional)
• Arduino libraries for MPU6050 and HMC5883L

Steps

1. Connect the quadcopter to the computer via USB cable.
2. Install the necessary libraries for the sensors in Arduino IDE (check the datasheet).
3. Load a sample sketch that reads data from the sensors and sends it to the serial monitor (check the datasheet).
4. Verify the correct reception of data on the serial monitor.
5. Configure the quadcopter for flight use, adjusting PID if necessary.
6. Test the quadcopter on a stable and safe surface.

Example code

// Esempio di codice Arduino
#include <Wire.h>
#include <MPU6050.h>
#include <HMC5883L.h>

MPU6050 accelgyro;
HMC5883L compass;
void setup() {
  Serial.begin(9600);
  Wire.begin();
  accelgyro.initialize();
  compass.initialize();
}
void loop() {
  if (accelgyro.getMotion6(&ax, &ay, &az, &gx, &gy, &gz)) {
    Serial.print(ax); Serial.print(", "); Serial.print(ay); Serial.print(", "); Serial.println(az);
  }
  compass.read(compassData);
  Serial.print("X: "); Serial.print(compassData.x);
  Serial.print(" Y: "); Serial.print(compassData.y);
  Serial.print(" Z: "); Serial.println(compassData.z);
}
